PRECAUTIONS PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AKS007X5
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along

with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:
● To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.
● Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
● Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Wiring Diagrams and Trouble Diagnosis AKS007X6
When reading wiring diagrams, refer to the following:
● Refer to GI-15, "How to Read Wiring Diagrams" .
Refer to PG-3, "
POWER SUPPLY ROUTING CIRCUIT" .
When performing trouble diagnosis, refer to the following:
● Refer to GI-11, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES" .
Refer to GI-27, "
How to Perform Efficient Diagnosis for an Electrical Incident" .

System Description AKS005T3
BASE SYSTEM
Refer to Owner's Manual for audio system operating instructions.
Power is supplied at all times
● through 15A fuse (No. 32, located in the fuse and fusible link block)
● to audio unit terminal 6
● to A/C and AV switch terminal 1 and
● to display control unit terminal 1 (with navigation system) or display unit terminal 1 (without navigation sys-
tem).

With the ignition switch in the ACC or ON position, power is supplied
● through 10A fuse [No. 6, located in the fuse block (J/B)]
● to audio unit terminal 10
● to A/C and AV switch terminal 2 and
● to display control unit terminal 10 (with navigation system) or display unit terminal 2 (without navigation
system).
Ground is supplied through the case of the audio unit.
Ground is also supplied
● to A/C and AV switch terminal 5
● to display control unit terminal 3 and 13 (with navigation system)
● to display terminal 1 (with navigation system) and
● to display unit terminal 6 and 15 (without navigation system)
● through body ground M35, M45 and M85
● to option connector for satellite radio receiver terminal 10
● through body ground B15 and B45.
Audio unit, A/C and audio controller are connected by FPC (Flexible Print Circuit).
A/C and audio controller integrates A/C switches and audio switches.
When A/C and audio controller is pushed to audio switch, it sends audio signal to audio unit.
Then audio signals are supplied
● through audio unit terminals 1, 2, 3, 4, 13, 14, 15, and 16
● to terminals 1 and 2 of front door speaker LH and RH
● to terminals 1 and 2 of rear door speaker LH and RH
● to terminals 1 and 2 of instrument speaker LH and RH.
When one of audio steering wheel switch is pushed to volume up, seek up, or mode ON, resistance in steering
switch circuit changes depending on which button is pushed.
When one of audio steering wheel switch is pushed to volume down, seek down, or power ON, resistance in
audio steering wheel switch circuit changes depending on which button is pushed.
BOSE SYSTEM
Refer to Owner's Manual for audio system operating instructions.
Power is supplied at all times

● through 15A fuse (No. 32, located in the fuse and fusible link block)
● to audio unit terminal 6
● to woofer terminal 1
● to A/C and AV switch terminal 1 and
● to display control unit terminal 1 (with navigation system) or display unit terminal 1 (without navigation sys-
tem),
● through 20A fuse [No.17, located in the fuse block (J/B)]
● to BOSE speaker amp. terminal 1.
With the ignition switch in the ACC or ON position, power is supplied
● through 10A fuse [No. 6, located in the fuse block (J/B)]
● to audio unit terminal 10
AV-8
AUDIO
Revision; 2004 April 2003 FX
● to A/C and AV switch terminal 2 and
● to display control unit terminal 10 (with navigation system) or display unit terminal 2 (without navigation
system).
Ground is supplied through the case of the audio unit.
Ground is also supplied
● to BOSE speaker amp. terminal 17
● through body ground B203 and B210,
● to A/C and AV switch terminal 5
● to display control unit terminal 3 and 13 (with navigation system)
● to display terminal 1 (with navigation system) and
● to display unit terminal 6 and 15 (without navigation system)
● through body ground M35, M45 and M85,
● to woofer terminal 2
● to option connector for satellite radio receiver terminal 10
● through body ground B15 and B45.
Audio unit, A/C and audio controller are connected by FPC (Flexible Print Circuit).

A/C and audio controller integrates A/C switches and audio switches.
When A/C and audio controller is pushed to audio switch, it send audio signal to audio unit.
Then audio signals are supplied
● through audio unit terminals 1, 2, 3, 4, 13, 14, 15, and 16
● to BOSE speaker amp. terminals 23, 24, 25, 26, 27, 28, 29, and 30.
Audio signals are amplified by the BOSE speaker amp.
The amplified audio signals are supplied
● through BOSE speaker amp. terminals 2, 3, 4, 9,10,11,12, 13, 14, 15, 16, 18, 19 and 20
